NASA Records Solar Blast of Epic Proportions

Posted by CmdrTaco on from the i-burnt-my-fingers dept.

Arvisp writes "As predicted, the a 'mega-filament' of solar magnetism erupted on Dec. 6th, producing a blast of epic proportions. NASA's Solar Dynamics Observatory recorded the action as the 700,000-km long structure lifted off the stellar surface and--snap!!--hurled itself into space. The eruption produced a bright coronal mass ejection (CME) observed by the STEREO-A spacecraft: video. Earth was not in the line of fire; the cloud should sail wide of our planet. Earth-effects might be limited to pretty pictures."

    I just read somewhere that these filament bursts contain cooler plasma, so they show as dark areas when observing the sun.

    For scale, 700,000km is half the diameter of the Sun.

    if they hit, as much as they hit, they have a huge effect on magnetosphere. and also can cause failures in electrical, electronical equipment.

    it is also possible that by presurizing earth's magnetic field, they are affecting all creatures on the planet. (Since all gets affected by the magnetism). shrinking magnetic field also means more cosmic rays coming in, i presume.

    energy of the blast, its emissions, may increase heating of the planet, i presume. but i dont remember it well.
